Results of the experiment on the skin using Retinaldehyde 0.5% for a period of 1 month on the forearm area.
Picture a shows the layer of keratin in the skin, where v is vehicle and r is retinaldehyde 0.5% 1 month, the level of keratin was clearly thickened.
Picture b shows the layer of transglutaminase in the skin, where v is vehicle and r is retinaldehyde 0.5% 1 month found levels of transglutaminase clearly thicker
Image c shows the layer of involucrin in the skin, where v is vehicle and r is retinaldehyde 0.5% 1 month, the level of involucrin was clearly thickened.
Picture d shows the filaggrin layer in the skin, where v is vehicle and r is retinaldehyde 0.5% 1 month, the level of filaggrin was clearly thickened.
